A solution containing 2.00 g of an unknown substance in 50.0 g ofcyclohexane freezes at 1.05°C. The normal freezing point. ofcyclohexane is 6.60°C and Kf = 20.4 °C/m. Both substances aremolecular.
a) Calculate the molality of the solution using ?T = Kfâ¢mâ¢i
b) How many moles of the unknown substance are in thissolution?
c) What is the molar mass of the unknown substance?
